Leonardo Lavalle Moreno (born 14 July 1967) is a former tennis player from Mexico, who turned professional in 1985. He represented his native country at the 1992 Summer Olympics in Barcelona, where he was defeated in the quarterfinals by Spain's eventual runner up Jordi Arrese. The left-hander won one career title in singles (Tel Aviv, 1991). He reached his highest singles ATP-ranking on 17 March 1986, when he became world No. 51.
Lavalle won the Wimbledon boys' junior singles and doubles title in 1985. His singles win was notable for the fact that the men's singles winner that year Boris Becker was younger than Leonardo. He was later a runner-up in doubles at Wimbledon in 1991 and a Wimbledon doubles semifinalist in 1989 and 1990.
